MARYLAND FLOW REPORT
Last Updated: December 22, 2025
Maryland's river systems are currently experiencing significantly lower-than-average streamflows, as indicated in the latest data collection. The Susquehanna River at Conowingo, a major waterway flowing through Maryland, has seen a slight increase in streamflow over the last 24 hours but remains 64.21% below the seasonal norm. The Potomac River system, with several key locations such as Paw Paw and Point of Rocks, also demonstrates below-normal streamflows, with the Potomac River Near Washington, D.C. operating at a 79.18% deficit. These conditions can affect not only water availability but also recreational activities, such as boating and fishing, that depend on healthier streamflow levels.
For river enthusiasts and outdoor adventurers, it's important to note that the Youghiogheny River, popular for whitewater rafting, has shown a notable increase in flow near Friendsville, yet it remains 47.61% below normal. The Monocacy River, another significant watershed for Frederick, shows a decrease in streamflow at Jug Bridge and Monocacy Blvd, which may impact local ecosystems and water resources. With several rivers and creeks experiencing flow reductions, enthusiasts should exercise caution as low water levels can expose hazards and affect the navigability of water trails. The current conditions do not signal immediate flooding risks due to the overall trend of reduced streamflow, but local communities should remain informed about potential for changes in weather patterns that could alter these conditions rapidly.
Maryland's flow conditions are heavily influenced by its location along the Atlantic coast and the Chesapeake Bay, as well as its varied topography. The state experiences a humid subtropical climate, with hot and humid summers and mild winters. Major surface flows include the Potomac and Patuxent Rivers, which feed into the Chesapeake Bay. Reservoirs and dams such as the Conowingo Dam and Loch Raven Reservoir also contribute to the state's hydrology. The state's watershed includes the Chesapeake Bay watershed, which covers 64,000 square miles and includes six states and the District of Columbia. Snowpack in the Appalachian Mountains can also impact flow conditions in the state. Overall, Maryland's flow conditions are complex and influenced by a variety of factors.
